High beam is Q543. Mine shows both Q519 and Q543 although I haven't experienced any DPF related issues or warning/fault lights. My car is at the dealer for both these updates at present. Current: Volvo XC90 T8 Inscription Pro PHEV with some optionals on top

Had my lights done today & the dpf upgrade or whatever it is,dealer done loads of miles in my car which I was a bit peed off about considering they don't tell you.
Anyway the lights are spot on so I'm happy with that

Got my car back today after AHBA and DPF updates, rectifying (minor) seat leather fitting issues and silencing a faint knocking noise from the rear.

AHBA is now available in the menu and I can see the corresponding icon illuminated in the instrument panel. Couldn't get it to work during my quick test drive because there are street lights everywhere so it wasn't dark enough. Hope to see it in action during the next out of town drive.

The car was returned with +75 miles on the clock. but all explainable: 22 miles round trip to the dealer, 25 miles round trip from dealer to trim company and 28 mile round trip for DPF regeneration. Current: Volvo XC90 T8 Inscription Pro PHEV with some optionals on top
